Abstract: A two layer planar multicontact switch including a first substrate layer having a plurality of parallel conductive lines deposited on the upper surface thereof and a second diaphragm layer located over the substrate layer and having a plurality of parallel conductive lines deposited on the lower surface thereof. The conductive lines on the substrate are normal to the conductive lines on the diaphragm such that a plurality of matrix switch intersections are formed. The conductive lines on the substrate and the diaphragm have insulating material selectively deposited thereon to electrically isolate the upper and lower conductive lines except at the points of intersection. The diaphragm layer may be mechanically depressed at the intersection points to selectively connect the upper lines with the lower lines to form switch closure contacts. The diaphragm and the substrate are formed from transparent material so that the switch can be employed in combination with a visual display.

Abstract: Kontaktflächen für Tasten oder Tastaturen, bei denen Leiterbahnen zu Kontaktflächen (6, 7) geführt sind.
Zweck der vorliegenden Erfindung ist es, die im Siebdruckverfahren aufgebrachten Kontaktflächen (6, 7) so zu gestalten, daß zweimaliger Siebdruckvorgang erübrigt. Nunmehr bestehen die Kontaktflächen (6, 7) aus auf einer Basis (1) aufgebrachten Graphitflächen, die mit jeweils einer großflächig als Elektrode (2, 3) gestalteten Leiterbahn seitlich kontaktiert sind.Abstract translation: 键或键盘的接触表面，其中导体路径被馈送到接触表面（6,7）。 本发明的目的是设计通过丝网印刷工艺施加的接触表面（6,7），使得不需要双丝网印刷工艺。 接触表面（6,7）现在由施加到基座（1）上的石墨表面组成，该石墨表面通过每个壳体中的大面积导体路径与侧面接触，设计为电极（2 ，3）。

Abstract: @ A membrane switch panel has a printed circuit base board (20) carrying bare copper electrical circuitry (26) and contacts (26 & 28). A flexible, non-elastomer, laminar membrane (22) overlays the board (20) and also carries a bare-copper contact (24). An electrically insulating spacer (3) is provided between the board (20) and the membrane, but it is provided with an opening to allow the contact (24) upon local depression of the membrane to bridge the contacts (26 & 28) in the base board (20).
The membrane (22) is adhesively sealed to the base board (20) enclosing an atmosphere of limited tarnishing ability for the contacts (20, 26 & 28) to maintain a low contact resistance and allow non-precious metals to be used for contacts.Abstract translation: 薄膜开关面板具有承载裸铜电路（26）和触点（26和28）的印刷电路基板（20）。 柔性非弹性体层状膜（22）覆盖板（20）并且还承载裸铜触点（24）。 电绝缘垫片（3）设置在板（20）和膜之间，但是其设置有开口，以允许接触（24）局部压下膜以将接触件（26和28） 基板（20）。 膜（22）被粘合地密封到基板（20）上，该基板（20）包围接触件（20,26和28）的有限的玷污能力的气氛，以保持低的接触电阻并且允许非贵金属用于接触。
